### Where power and signal conductors must cross, they shall cross at right angles to minimize coupling.
−### Analog and instrument signal cabling shall be shielded, with the shield grounded at one end only per IEEE 518, to limit electrical noise on low-level signals.
+### Analog and instrument signal cabling shall be shielded, with the shield grounded at one end only per IEEE 518 and [[sync/instrumentation-and-control-cable]], to limit electrical noise on low-level signals.
### A minimum separation of 1 in. shall be maintained between parallel runs of power wiring and signal wiring, increasing the separation where higher-energy or drive output circuits are present.
…260 unchanged lines
## A spare DC power supply shall be provided where the panel serves a critical process and loss of control power would interrupt operation.
